commit 271e1b86e691 is breaking DMA uart on SoCFPGA

[Dinh Nguyen]

Hi Vinod,

It appears that commit 271e1b86e691 "dmaengine: pl330: add quirk for
broken no flushp" is breaking uart dma on SoCFPGA. This commit is in
linux-next(next-20160210).

Doing a bisect pointed to commit 271e1b86e691, but I had to also revert
the following commits (86a8ce7d4103 "dmaengine: pl330: add max burst for
dmaengine") and (848e9776fee4 "dmaengine: pl330: support burst mode for
dev-to-mem and mem-to-dev transmit") as well because the build would
fail if I only revert 271e1b86e691.

The SoCFPGA platform is being tested on Olof's board farm and is failing
multi_v7_defconfig build because the PL330 DMA is enabled in this defconfig.

After doing reverts of those 3 commits, the socfpga platform is able
boot completely again with multi_v7_defconfig.
